(For comparison, British Muslims in my experience don't think of their religion as making the same demands Muslims in the Middle East typically imagine.)

This is because these British Muslims (unlike those you typically find sitting in British mosques, for instance) are essentially agnostic or closet atheists. There is absolutely no "reinterpreting" of say, the five pillars of Islam, which includes perhaps most significantly, their burdensome daily prayers. If they are not performing them as required by every recognized sect of Islam, you can be pretty sure they are not Muslim and know it - but for some reason they value the Muslim identity even in Britain so they still "practice" Islam, but differently. I don't think the case with Hindus is all that much different.
